CREATING TOMORROW’S SOLUTIONS

SILICONE GEL SOLUTIONS

Research, Improve, Research.We have been researching silicones since 1947. The development of novel silicones is linked to the WACKER name around the world. As an internationally active company, we produce silicones for almost every application and sector. This includes many well-known car, semiconductor and PV manufactures. Hence, we know the require-ments of these industries – including the worldwide cost pressure. We are continuously researching new solutions, so you can face this competition successfully.

SILICONE GEL A SOFT MATERIAL FOR HARD DEMANDS

ELASTOSIL®, POWERSIL®, SEMICOSIL® and WACKER SilGel® are registered trademarks of Wacker Chemie AG.

With WACKER silicone gels, you can protect sensitive components against external influences. Silicone gels are water-repellent, have high electric strength and dampen mechanical vibrations excellently.

Silicone gels’ special feature is their ex-traordinary flexibility. In a silicone gel, the individual polymer molecules are inter-connected to form a loosely crosslinked network. In this way, the silicone chains are able to yield whenever they encoun-ter a hard surface.

Since silicone gels are so resilient, they can absorb thermomechanical stress bet-ter than any other materials. That’s why they are ideal for the encapsulation of material systems such as electronic as-semblies and solar cells. Thanks to their outstanding electrical properties, they prevent leakage currents and flashovers. Another interesting characteristic of sili-cone gels is their excellent temperature tolerance. Whether -50 °C or +200 °C – their physical and technical properties remain unchanged, even after several thousand hours in service. In short, most WACKER silicone gels are probably more durable than the devices or assemblies that they encapsulate.

We have set up technical centers across the globe to offer all manner of support for product selection, manufacturing and end-product specification. For more information, visit www.wacker.com

UNIQUE IN FLEXIBILITY AND PURITY

WACKER silicone gels permanently cushion thermomechanical stress. Their purity ensures durable electrical functionality and provides protection against corrosion. Exceptional in their Resilience Whether computer or solar module, modern industrial commodities consist of numerous materials with different coefficients of thermal expansion (CTEs). For the materials to bond together per-manently, they require a substance with high elasticity, because thermomechani-cal stress should not be transferred to adjoining components. Silicone gels are ideal for this.

Another advantage of silicone gels is that, due to their chemical structure, they are extremely temperature-stable. Standard silicone gels remain flexible at temperatures ranging from -50 °C to +200 °C. Low-temperature silicone gels even retain their elas-ticity down to -100 °C (see Chart 1).

Chart 1: WACKER SilGel® 612 and SEMICOSIL® 920 LT, Elastic Modulus vs. Temperature

Soft and deformable: silicone gels feature the lowest modulus of elasticity of all available mate-rials. This allows them to withstand mechanical pressure and thermal stress particularly well. The images illustrates the measurement of penetration depth. For very soft silicone gels, this is typically between 50 and 70 mm/10.

High Chemical Purity GuaranteedBased on how they are produced, sili-cone gels from WACKER are highly pure. The low amount of ionic impurities also increases the operational reliability of your products. For example, WACKER SilGel® silicone gels, which are often used in the electrical industry. At a maximum of 10 ppm, they only contain traces of impurities such as metal ions or halides (see Chart 2).

SEMICOSIL® silicone gels are a lot purer still. They are already produced from purified raw materials. In addition, they undergo a regular, standardized quality test: the pressure cooker test. As depict-ed in Chart 2, we thus achieve typical ion contents of less than 2 ppm.

OUTSTANDING ELECTRICAL PROPERTIES AND HEAT STABILITY

High electrical strength: in the transmission and distribution industry, silicone gels can be used to encapsulate cable accessories, for example.

7

Ever more powerful devices are raising the demands on dielectric strength, insulation resistance and tracking resistance. With silicone gels from WACKER, you can stay on the growth path.

Outstanding Electrical ParametersWith a silicone gel from WACKER, you have a material with outstanding electrical parameters. The reason for this is silicone gels’ high chemical purity and very low water uptake. In addition, silicones are exceptionally aging resistant due to their chemical structure. As a result, they maintain their specific electrical proper-ties for a long time.

Resistant to Heat and ColdFaster, higher, hotter – miniaturization and growing functionality increase the heat that electric and electronic assem-blies give off. At the same time, the products must function flawlessly under extremely cold conditions, too.

WACKER’s standard silicone gels retain their favorable electrical and mechanical properties over a temperature range of -50 °C to +180 °C – even after several thousand operating hours. Strong radia-tion, ozone gas and high atmospheric humidity also only alter the silicone gels’ properties very slightly. Furthermore, there are specialty silicone gels with low-temperature flexibility and high-temperature stability for extreme environments.

WACKER’s standard silicone gels have high inherent tack and self-healing properties. They dampen mechanical and thermal stress in an exemplary manner.

Excellent Inherent TackWACKER silicone gels really display their strength when it comes to difficult-to-bond surfaces. Thanks to their good inherent tack, they form firm and durable bonds to virtually all standard materials.

Self-Healing EffectThanks to their good self-healing proper-ties, you can touch up and repair WACKER silicone gels without pretreatment by applying more of the liquid silicone gel to the already cured gel surface.

Silicone Gels for Diverse ApplicationsWACKER’s standard silicone gels differ in viscosity, processing and curing speeds, transparency and color. As shown in the table, the products are available as two-part systems in a mixing ratio of either 1:1 or 10:1. The 10:1 mixtures are so-called modular systems. Find out how you can use these to enhance your pro-cess control on page 14.

Key Features of WACKER’s Standard Silicone Gels

10

SPECIALTY SILICONE GELS –OPTIMIZED FOR EXTREME DEMANDS

Our standard silicone gels already combine a large number of excellent properties. For our specialty silicone gels, we have additionally enhanced individual parameters, such as tem-perature resistance.

Designed for Fast Processing Low-viscosity WACKER SilGel® 619 is easy to apply and flows quickly. Due to its very high reactivity, it cures rapidly. This makes for extremely quick in-line application with large quantities per unit time.

Optimized for Energy TransmissionPOWERSIL® silicone gels feature opti-mized and separately monitored electrical parameters such as dielectric strength and tracking resistance. Their application field is insulators for the transmission and distribution industry that are exposed to weathering for decades.

Ready for Extreme Temperatures Whether desert or polar circle: at WACKER, you can find silicone gels that retain their properties even at extreme temperatures. For example, low-temperature-flexible SEMICOSIL® 900 LT and SEMICOSIL®

920 LT and high-temperature-resistant SEMICOSIL® 915 HT. After all, vehicles must still function in Alaska at -60 °C, just like power modules must still func-tion at +200 °C service temperature.

Resistant to Aggressive MediaFor automotive and aircraft engineering, we have developed silicones that retain their favorable properties even when in contact with fuels or acidic exhaust gases. In the product table, you can find this special fluoro-silicone gel under the tradename SEMICOSIL® 928 F.

TOUGH SILICONE GELS –WHEN ADDITIONAL MECHANICAL STABILITY IS REQUIRED

Typical silicone gels cure to form soft products. However, some applications require enhanced mechanical protec-tion. For this, we offer you so-called tough silicone gels with increased hardness.

Soft silicone gels typically have a modu-lus of elasticity of 5 to 10 kPa. This is too low for applications such as the potting of solar junction boxes. For this purpose, we have developed silicone gels with increased hardness (see table). The mea-surement parameter is no longer material penetration, but Shore 00 hardness.

Power semiconductors are being manu-factured in ever higher quantities. To reduce cycle times, encapsulants that cure rapidly are in demand. Our modular system offers you unique flexibility. Depend- ing on the catalyst of choice, you can specify the curing time yourself. For example, a gel time of about 3 hours is achieved with a platinum catalyst at 20 °C

ELASTOSIL® CAT PT will let you achieve longer pot lives with moderately fast curing. The significantly more reactive ELASTOSIL® CAT PT-F will allow you to realize shorter cycle times. You can achieve very fast curing with the UV-activated ELASTOSIL® CAT UV, while very long potlives are possible at the same time.

and of approx. 20 minutes in an oven at 120 °C; the gel time is less than 3 min-utes at room temperature in the presence of UV radiation and a UV catalyst. The product’s end properties remain con-stant, independent of the curing process.
